TEIEEPOBARY BINDER.

' Application filed December To all whom it may concern:

Be it known that I, WILLETT M. RAYNOR, a citizen of the United States of America, and resident of New York, in the county and State of New York, have invented certain newand useful Im rovements in Temporary Binders, of which t e following is a specification.

This invention relates to loose leaf binders and particularly to those having sectional urpose of increasing addition of leaves to any practical extent.

- The objects of this invention are: first, to provide a novel binder in which the unoccupied portion of the binding posts are confined within a housing, comprising one of the clips or binder members; second, the provision of means for locking the posts regardless of their position with relation to the housing or binder section so long as any portion of the posts project within the housing; and third, to provide binding members and sectional posts with sections of such length with relation to the binder members that the said binder members, when fastened to the osts, may always lie flush or in contact wit 1 the leaves. his invention might be termed a flush leaf binder, in which the posts and binding means are invisible.

With the foregoing and other objects in view, the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more is a detail view of one of the binder members,

looking at the end thereof; Fig. 3, is a detail view showing the sectional posts and the relation of the housings thereto.

In the drawings A and B, denote the hinding members, also termed clips which are approximately C-shaped in cross section, the

contiguous or mnerportions of the two inembers being parallel and adapted, when leaves are inserted, to bear on said leaves. The outer walls of the clips or casings are referably struck up or bent to form interna channels a and b, respectively, thus producing Specification of Letters Patent.

what may be termed for the purpose of receiving the loc g mechanism and further for producing space for the accommodation of the binding posts 0, which pass through the apertures 11-, in themember A.

The binding posts are anchored in the member B, and extend through the a ertures b, of said member. The member A provided with stationary jaws D, at the aperproximately conforming to the contour of t e osts. The posts are forced against the jaws or the purpose of retaining the posts locked therein, by any suitable mechanism, operated from the exterior of the members, and I have found in ractice that the lockin members described in my a plication filed April .22, 1907, bearing erial Number $69,551, is well adapted for usein this connection and said locking mechanism comprises the sliding dogs E, having slots e, to receive the guide pins F. The dogs are held normally away from the pins C, by springs G, which have the ends connected to the dogs and to the pin. 9, which pin g, is in the binding member. The dogs are projected into engagement with the posts C, against the action of the springs G, by the double cam H, on the face of the sliding plate I, which plate has a slot i, to receive the in (1. The inner ends of the dogs have beveleclbnds on the angle of the double cam ll, as shown in dotted lines and as said plate I, is forced out by the key J, the cams project the dogs.

sections which are applied to the posts heretofore described are preferably of the same length as the posts attached to the member B, and the sections ma be joined in any suitable manner but pre 'erably bv threaded shank and socket connections whereby the succeeding sections of the extension posts may be threaded into each other.

In carrying out the invention it is desirable that the extensions be practically uniform in length and that their length shall be no greater than the depth of the housing to which they are apolied, for, if the length is greater than the depth of the housing, the parallel sections of said housings could not contact with the leaves applied to the posts, owing to the fact that the ends of the posts would contact the inner wall of a member before the lower portion thereof crmtactec housings des' 'ned tures a, said jaws having recessed ends d, a

The extensions 0, of the posts that is, thev cupied by leaves are conceale or other cover is with the leaf. By enlaring the housing, that is increasing the dept "of said housing, the sections, of the posts may be of snfiicientj length to receive ,a given number of additional sheets before it becomes necessary to increase the length of the 0st by added sections andthose portions 0 the osts-not 00 d within the housing.

Another advantage for the construction of {the-housing as shown and described, is that it permits a smooth finish when the leather applied thereto.-

I claim: v
